Hacking the ADALM-PLUTO is possible (and encouraged). In this case - what we mean by hacking is the act of programming or extending the functionality or use cases of the PlutoSDR, in a spirit of playfulness and exploration. In order to do that, you should be familiar with the device, from a user and developer standpoint.
Many aspects of the PlutoSDR are based from the AD-FMCOMMS3-EBZ, and you should be familiar with that, as it will help understand how to extend the PlutoSDR.
